This is a BRAND NEW-In-The-BOX Universal Furnace Relay with a 24 volt coil. It has two completely independant circuits with 2 seperate "Feed" terminals 2 "Normally Open" set of contacts and 2 "Normally Closed" set of contacts. Many OEM relays do not have as many terminals on them as this one does- simply disregard any extra terminals. They are there to make the relay a universal replacement. We use them for furnace and air conditioning repairs but they are great for any purpose. Thanks for looking and good luck!
Relays are switches that open and close circuits electrically. In most HVAC equipment a low voltage coil relay (24 vac) is energized in order to open or close a higher voltage (usually 120-240) circuit.
